Precautions and Safety Notices

1. When replacing the lamp, use care to avoid burns to your fingers. The lamp becomes very hot during operation.

2. Never touch the lamp with your fingers as body oil transferred to the lamp can damage the lamp’s useful life.

3. Never drop the lamp or jar it in any manner. This may cause the lamp to burst.

4. This projector is provided with a high voltage circuit for the lamp. Do not touch any electric part or component after the projector has been turned on and is operating. Doing so could induce a severe shock causing injury or death.

5. Do not touch the exhaust fan, nor block its air flow, during operation, as the fan is hot.

6. Use only the cables which are included with the projector, or are specified in this manual.

7. Ensure that screws are tightened properly. Screws not tightened fully may result in injury or accidents.

8. Since the lamp is made of glass, do not drop the unit and do not scratch the glass.

9. Do not reuse the old lamp. This could cause the lamp to explode.

10. Be sure to turn off the projector and unplug the AC power cord before replacing the lamp.

11. Do not use the projector with the lamp cover removed.

Disposal : For disposal of spent lamps, always consult federal, state, local and

provincial hazardous waste disposal rules and regulations to ensure

proper disposal.

Caution : This lamp emits ultra violet (UV) radiation and operates at high

pressure.

This lamp may only be used in enclosed fixtures that comply with

UL1572.

Due to the high luminous efficacy, the UV radiation which the lamp

emits and the high pressure within the lamp, P-VIPâ lamps may only be

operated within enclosed, purpose-built housings.
